A roast turkey is taken from an oven when its temperature has reached 185°f and

Answer;

High temperature and pressure

Explanation;Nuclear fusion in stars and supernovae is the primary process by which new natural elements are created. Nuclear fusion occurs in presence of very high temperature and high pressure, which one of the common characteristics of many stars.High temperature gives hydrogen atoms enough energy to overcome the electrical repulsion between the protons. Fusion requires temperatures about 100 million Kelvin.  High pressure squeezes the hydrogen atoms together. For example the sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core.
